Peanuts are very high in oil and fat which is great for birds. They are most economically fed through a wire mesh feeder which discourages "pesty" birds and squirrels (if you feed the larger whole spanish peanuts). While almost all birds will eat peanuts, they are favored by the "clingers" like titmice, chickadees and all of the woodpeckers. We carry two grades of peanuts; larger, whole spanish peanuts and pickouts (halves and pieces). Available in 5lb, 10lb & 20lb bags
